Fast Neutron Radiography at an RFQ Accelerator System
Presented by Mr. Graham DANIELS on 1 Jul 2015 from 15:00 to 15:20
Type: Oral Presentation
Track: Track B - Nuclear, Particle and Radiation Physics
Improvements have been made to the 4MeV Radio Frequency Quadrupole Accelerator (RFQ) at Necsa and the HEBT focusing system. The option to change the target configuration to a solid boron carbide target has been made, for the specific purpose of producing a fast neutron source (1 - 10 MeV at 10<sup>11</sup> n.s<sup>-1</sup>.cm<sup>-2</sup>) and two distinct gamma rays (4.43 MeV and 15.11 MeV). This interrogating radiation has been used for studies in the field of cultural heritage and fluid flow, by conducting fast neutron radiography (FNR) on samples from the respective disciplines. The nature of the developments will be highlighted and the investigation into anthropology and the density evolution in mineral systems, presented, with the comparisons made to theoretical simulations and experiments conducted at the fast neutron facility at Physikalisch Technische Bundesanstalt, Braunschweig.
